Abstract

An optical isolator with a TiO 2/(CeY) 3Fe 5O 12 guiding layer was studied. A nonreciprocal phase shift was calculated in the magneto-optic waveguide with the TiO 2/(CeY) 3Fe 5O 12 guiding layer at a wavelength of 1.55 μm. By employing a multimode interference coupler as coupling devices, the total device length of approximately 600 μm was achieved. An interferometric optical isolator with distinct layer structures, which could be operated in a unidirectional magnetic field, was also designed.
